Banks Power 42135 Ram-Air Intake System

The Banks Power 42135 Ram-Air Intake System delivers astonishing gains in airflow, air density and power for your 2004.5-2005 GM 6.6L Duramax LLY. All Banks Ram-Air Intakes start out as CAD software prototypes that are put through flow simulation and the design is refined until the simulation shows optimal performance. A hardware prototype is then manufactured, and the design is validated on a flowbench, dyno tested, and then vehicle tested. With a giant 7-1/8” inlet, streamlined components, and an enclosed cold-air box that keeps hot engine air out of the intake, this cold air intake flows up to 57% better than the factory intake. 

The Banks Power 42135 Ram-Air Intake System large cotton gauze air filter requires fewer cleanings than competitive filters (the stock's small paper filter is not reusable). With up to +39 hp and +69 lb-ft more than a tuner alone, this intake can help improve mileage, lower EGTs, and create less black smoke. Black smoke is an indicator of unburned fuel, meaning its power lost out of the tailpipe. This also equates to better mileage, lower EGTs, and less smoke. This intake’s unique 4.5" bellows accommodate engine movement, which helps prevent component damage and prolongs service life. This cold air intake is designed to not cause fault or error codes.

Banks exclusive Super-Scoop is an add-on product to the Ram-Air Intake System. Super-Scoop connects below the front bumper, forcing a big charge of cool, pressurized ram air into the Ram-Air Intake's air filter housing. Because the air is drawn from outside the engine compartment, it has greater density and makes more power than warmer engine air. Rainwater and debris are funneled out of the bottom.
